Supplier of Coltan. Coltan is a dull black metallic ore from which the elements niobium and tantalum are extracted.
We have currently have available 1000MT of Coltan / Tantalite with a purity of 30% in DRC with capacity to deliver 500 - 1000MT on a monthly basis. The chemical properties are as follows: a) Tantalum: 30.44 % Ta 40.01 % Ta2O5 b) Iron: 1.87 % Fe 10.98 % FeO c) Oxygen: 10.69 % O Coltan is (short for columbiteâ??tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is the tantalite. Tantalum from coltan is used to manufacture tantalum capacitors which are used for mobile phones, personal computers, automotive electronics, and cameras.
